Summary

The aim of this study is to investigate the effect of plantar two-point discrimination on hip-knee-ankle position sense in children with toe walking.The main questions it aims to answer are: * Are two-point discrimination and light pressure sensation in the plantar region affected in children with idiopathic toe gait? * Does the two-point discrimination in the plantar in general and the heel in particular affect the position sense of the hip-knee and ankle?

Detailed description

Children who tend to walk on toes after they should have developed a heel-toe gait are diagnosed with idiopathic toe walking (ITW).Cerebral palsy, muscular dystrophy, and orthopaedic problems such congenital talipes equinus are some of the diseases that are frequently linked to a toe-walking gait. A diagnosis of ITW is made when there is no physical or medical cause for the absence of a heel strike. Five percent of healthy children are estimated to have ITW, and boys are more likely than girls to be affected. Reduced ankle range of motion is prevalent symptom in children with ITW. Since ITW often manifests as symmetrical tiptoe walking in children, reports showing a comparable bilateral reduction in ankle range of motion at both lower limbs indicate the symmetrical character of this gait type. Lower vibration perception thresholds, a tendency to be left-handed, and noticeable variations in sensory seeking and modulation scores are all characteristics of children with an ITW gait. The small fibers that innervate the cutaneous receptors (such as Merkel's cell, Pacinian corpuscles, Meissner's corpuscles, and Ruffini endings in the skin) are more crucial for postural control than the large fibers that innervate the major muscle spindles and the Golgi tendon organs. Standing balance control is more dependent on Merkel's cells and Ruffini endings (slow adapting receptors), which are in charge of touch and pressure sensitivity, than it is on Meissner's and Pacinian corpuscles (rapid adapting receptors), which are in charge of vibrotactile sensitivity.Additionally, it has been demonstrated that tactile sensation in the foot sole affects the activity of the tibialis anterior muscle as well as the regulation of gait pattern at lower limb joints. These investigations support the notion that cutaneous feeling is crucial for preserving postural and gait stability.The literature states that plantar pressure and sensory changes have disruptive effects on postural control.The aim of this study is to investigate the effect of plantar two-point discrimination on hip-knee-ankle position sense in children with toe walking.

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	Two-point Discrimination Test	Two-point discrimination (2PD) is the ability to discern that two nearby objects touching the skin are truly two distinct points, not one. It is often tested with two sharp points during a neurological examination and is assumed to reflect how finely innervated an area of skin is.
DIAGNOSTIC_TEST	Semmes-Weinstein monofilament test	Semmes-Weinstein monofilament test is used to assess light touch sensations.
